Although it is not the recommended approach, sourcing a completion
script is the simplest way to get people to try using shell completion.
Not allowing it for zsh has turned out to complicate shell completion
adoption. Further, many tools modify the zsh script to allow sourcing.
This commit allows sourcing of the zsh completion script.

Fixes#1831
By moving the check for help group existence to "ExecuteC()" we no
longer need groups to be added before AddCommand() is called. This
provides more flexibility to developers and works better with the use
of "init()" for command creation.

Fixes#1786
The --help, -h, --version and -v flags are normally added when the
`execute()` function is called on a command. When doing completion
we don't call `execute()` so we need to add these flags explicitly to
the command being completed.
Also, we disable all further completions if the 'help' or 'version'
flags are present on the command-line.

When a user has an alias in powershell, she will need to register that
alias for completion. To make that possible, we store the completion
logic into a scriptblock variable which can easily be accessed by the
user to register aliases.
For example, if the user defines an alias for `helm`:
PS> sal h helm
she will need to register the alias like so:
PS> Register-ArgumentCompleter -CommandName 'h' -ScriptBlock $__helmCompleterBlock

The format "go install github.com/kyoh86/richgo@latest" will work with
go 1.16 and higher. It will not work with go 1.15. However, since
installing "richgo" is only required for people who want to run the go
tests for the Cobra project itself, I feel it is ok to require go 1.16
or higher in this case.

Tab characters that introduce completion descriptions weren't properly
being handled with bash v3. This change fixes that.

PR #889 introduced a regression where the global variable $c is no
longer set when *custom_func is called. This is because $c is re-used
by mistake in the read loop.
This PR simply changes the name of the variable used in the loop.
